PIANO-FORTE MUSIC-RACK ILLUMINATOR.

SPECIFICATION forming part of Letters Patent No. 324,901, dated August 2.5, 1885.

Application filed January 10, 1885.

To all whom it may concern:

Be it known that we, HENRY WARD and JOHN S. U'r'rEn, citizens of the United States, residing at'Stockton, in the county ofSan J oaquin and State of Ualifornia, have invented certain new and useful Improvements in Piano- Forte Music-Rack l'lluminators, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation showing method of attachment to a square piano. Fig. 2 is a transverse section of the same. Fig. 3 is a side elevation of a portion, showing method of attachment to an upright piano. Fig. at is a transverse section of Fig. 3. Fig. 5 is a top view of the supportingstem of Fig. .1.

Similar letters of reference indicate corresponding parts.

The principal object of our invention is to provide means for illuminating the musicracks of piano-fortes by the use of such devices as may be readily attached to a piano.

The invention will first be described in con nection with the drawings, and then pointed out in the claim.

Let N represent the body of a square piano, to which is screwed a flange, H, having a neck, 1, over which is inserted the rear collar, F, of a supporting-stem, E, the collar F being fixed firmly in position by a thumb'screw, G, which screws into the top of the neck I of flange H. The stem E extends forwardly, and has at its forward end a collar, D, and reservoir or fountain A, for petroleum, having a neck, 6, which screws onto a tube-piece, b, which is inserted into collar D, and has at its top and just above collar 1) a threaded ring, 0, screwed upon it, and is formed with a shoulder at each end, so that the ring 0 and neck c may screw up tightly and still permit of a flexible joint. Into the ring 0 is screwed an elbow-tube, d, which (No model.)

tube O is of thin material at its top, so that when means of ignition are supplied at the perforations of its head the heat causes gas to be generated from the petroleum in the fountain A and connecting wick, which gas burns brightly and steadily and furnishes the means for illuminating the music-rack of the instrument, and dispenses with the use of lamps, 820. To attach to an upright piano, the neck 1 is bent so that the flange H may be vertical and be attached to the instrument M, as shown in Figs. 3 and 4t.

WVe are aware that some of the mechanism we have illustrated and described is not new; but,

that we claim as being of our invention 1s- The illuminator consisting of the plate H, having the neck I and screw G, the stem E, having the collars F 1), the reservoir A, the tube B, and the burner consisting of the perforated cap j, substantially as shown.

In testimony whereof we affix our signatures in presence of two witnesses.

HENRY WARD.
